Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filter cloth rinsing rack for a plate and frame filter press. Background Technology

[0002] Wastewater treatment generates a large amount of sludge. This sludge, which settles through inclined tubes, needs to be further dewatered by a plate and frame filter press before it can be reused. The filter cloth in the plate and frame filter press needs to be cleaned regularly to prevent the sludge adhering to it from affecting filtration or the flow of wastewater. The existing cleaning method is to place the filter cloth in a cleaning machine and clean it by stirring. This cleaning method can easily cause the filter cloth to break during the cleaning process, and there is also the problem of incomplete cleaning. Utility Model Content

[0003] This utility model provides a filter cloth washing rack for plate and frame filter presses to overcome the shortcomings of the prior art, solve the problems of incomplete cleaning and easy damage of filter cloth, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A filter cloth washing rack for a plate and frame filter press includes a base plate with a pair of vertical rods welded to it. Each vertical rod has a pair of fixing mechanisms. The upper fixing mechanism is fixed to the upper end of the vertical rod with screws, while the lower fixing mechanism is movably sleeved on the lower end of the vertical rod. The upper end of the filter cloth is fixed by the fixed fixing mechanism, and the lower end is fixed to the lower end of the filter cloth. The filter cloth can be stretched taut by the lower fixing mechanism, and then washed with water. This method avoids damage to the filter cloth and ensures effective cleaning.

[0006] Furthermore, the fixing mechanism includes a ring sleeve fitted on the vertical rod, screws passing through the upper ring sleeve and the vertical rod, a back plate welded between the ring sleeves, a pair of protrusions formed on the back plate, a guide rod perpendicular to the plane of the back plate connected to the protrusions by threads, a connecting protrusion sleeved on the guide rod, an inner pressure plate welded to the lower end of the connecting protrusion, an L-shaped plate welded to the inner pressure plate, a hinge shaft rotatably mounted on the L-shaped plate, an inner top rotating plate welded to the lower end of the hinge shaft, the inner end of the inner top rotating plate having a convex arc structure, a liner plate formed on the back plate, the inner end of the inner top rotating plate abutting against the back side of the liner plate. When the filter cloth is clamped, the inner pressure plate and the back plate can be fixed at both ends of the filter cloth by rotating the inner top rotating plate, wherein the guide rod plays a guiding role in the movement of the inner pressure plate.

[0007] Furthermore, a limit nut is threaded onto the guide rod, and the limit nut is located on the outside of the inner pressure plate to limit the movement of the inner pressure plate.

[0008] Furthermore, the lower end of the inner pressure plate is bent outward to form an arc-shaped strip to prevent the edges of the inner pressure plate from damaging the filter cloth.

[0009] Furthermore, the inner pressure plate has transverse holes, and an inner insert strip is welded to the inner wall of the back plate, passing through the transverse holes. The outer end face of the inner insert strip has an arc-shaped structure. A lower transverse hole is provided at the lower end of the back plate, and a protrusion passes through the lower transverse hole. The protrusion is welded to the inner wall of the inner pressure plate, and its outer end face has an arc-shaped structure. The inner insert strip, the protrusion strip, and the transverse and lower transverse holes facilitate the fixation of the filter cloth, thereby improving the fixation effect of the filter.

[0010] Furthermore, the outer end of the inner top rotating plate is bent downwards to form an end plate, on which a pull rod is threaded. A gripping rod is welded to the outer end of the pull rod, and the other end of the pull rod is threaded to an inner column. A spring is fitted onto the pull rod, with the inner end of the spring abutting against the outer end of the inner column and the outer end of the spring abutting against the inner plate of the end plate. An insertion rod is welded to the other end of the inner column and is inserted into the liner plate. The insertion rod can lock the posture of the inner top rotating plate, making the inner top rotating plate perpendicular to the back plate, while the spring ensures the stability of the insertion limit of the insertion rod.

[0011] Furthermore, multiple slots are provided on the lower outer periphery of the vertical rod. A rotating protrusion is welded to the outer periphery of the ring on the fixing mechanism at the lower end. A pin is welded to the outer end of the rotating protrusion. End plates are provided at both ends of the pin. A torsion spring is fitted on the pin. The outer end of the torsion spring is fixed to the end plate. A rotating plate is rotatably provided on the pin. A rectangular groove is provided on the rotating plate. The rotating protrusion passes through the rectangular groove. A plate is provided on the inner end of the rotating protrusion. The plate passes through the slot. The inner end of the torsion spring is fixed to the rotating plate. A gripping part is provided on the outer end of the rotating plate. A concave rod is welded to the gripping part. Through the slots and the rotating plate, the fixing mechanism at the lower end can be fixed, thereby ensuring that the filter cloth is taut, which facilitates the rinsing operation. The torsion spring ensures the stability of the plate after it is engaged.

[0012] The advantages of the above technical solution are:

[0013] This invention uses a method of tightening the filter cloth to facilitate rinsing. Rinsing can quickly flush out sludge and prevent the filter cloth from being damaged. Attached Figure Description

[0018] like Figures 1-3 As shown, a filter cloth rinsing frame for a plate and frame filter press includes a base plate 1, a pair of vertical rods 2 welded on the base plate 1, and a pair of fixing mechanisms 3 provided on the vertical rods 2. The fixing mechanism 3 located at the upper end is fixed to the upper end of the vertical rod 2 by screws 31, and the fixing mechanism 3 located at the lower end is movably sleeved on the lower end of the vertical rod 2.

[0019] The fixing mechanism 3 includes a ring 30 sleeved on the vertical rod 2, and a screw 31 passing through the ring 30 and the vertical rod 2 located at the upper end. A back plate 32 is welded between the rings 30. A pair of protrusions 33 are formed on the back plate 32. A guide rod 34 perpendicular to the plane of the back plate 32 is threadedly connected to the protrusions 33. A limit nut 35 is threadedly connected to the guide rod 34. A connecting protrusion 36 is sleeved on the guide rod 34. An inner pressure plate 37 is welded to the lower end of the connecting protrusion 36. An arc-shaped strip 38 is formed by bending outward at the lower end of the inner pressure plate 37. An L-shaped plate 41 is welded to the inner pressure plate 37. A hinge shaft 42 is rotatably provided on the L-shaped plate 41. An inner top rotating plate 43 is welded to the lower end of the hinge shaft 42. The inner end of the inner top rotating plate 43 has a convex arc-shaped structure. A liner is formed on the back plate 32. The inner end of the inner top rotating plate 43 abuts against the back side of the liner.

[0020] Multiple slots 20 are provided on the lower outer periphery of the vertical rod 2. A rotating protrusion 50 is welded to the outer periphery of the ring 30 on the fixing mechanism 3 at the lower end. A pin is welded to the outer end of the rotating protrusion 50. End plates 56 are provided at both ends of the pin. A torsion spring 52 is sleeved on the pin. The outer end of the torsion spring 52 is fixed to the end plate 56. A rotating plate 53 is rotatably provided on the pin. A rectangular groove 55 is provided on the rotating plate 53. The rotating protrusion 50 passes through the rectangular groove 55. A plate 54 is provided on the inner end of the rotating protrusion 50. The plate 54 passes through the slot 20. The inner end of the torsion spring 52 is fixed to the rotating plate 53. A gripping part 57 is provided on the outer end of the rotating plate 53. A concave rod 58 is welded to the gripping part 57.

[0021] In this embodiment, when cleaning the filter cloth, the operator places the upper end of the filter cloth between the back plate 32 and the inner pressure plate 37. Then, the operator rotates the inner top rotating plate 43. When the inner top rotating plate 43 rotates, it forces the inner pressure plate 37 to move towards the back plate 32, thereby clamping the filter cloth between the inner pressure plate 37 and the back plate 32. After clamping, the length direction of the inner top rotating plate 43 is perpendicular to the back plate 32. Then, the lower end of the filter cloth is fixed between the inner pressure plate 37 and the back plate 32 located at the lower end. Next, the inner pressure plate 37 and the back plate 32 located at the lower end are moved downward to make the filter cloth taut. During the movement, the gripping part 57 needs to be pressed inward to move the clamping plate 54 out of the clamping groove 20. When the filter cloth is taut, the clamping plate 54 is clamped in the clamping groove 20 under the action of the torsion spring 52. Then, the filter cloth is cleaned by spraying water onto the filter cloth.

[0022] In some embodiments, the inner pressure plate 37 has a transverse hole 39, and an inner insert 40 is welded to the inner wall of the back plate 32. The inner insert 40 passes through the transverse hole 39, and the outer end face of the inner insert 40 has an arc-shaped structure. A lower transverse hole 45 is provided at the lower end of the back plate 32, and a protrusion 44 passes through the lower transverse hole 45. The protrusion 44 is welded to the inner wall of the inner pressure plate 37, and the outer end face of the protrusion 44 has an arc-shaped structure. In this embodiment, the inner insert and the protrusion improve the fixing effect on both ends of the filter cloth.

[0023] In some embodiments, the outer end of the inner top rotating plate 43 is bent downward to form an end plate 46, a pull rod is provided on the end plate 46, a holding rod 47 is welded to the outer end of the pull rod, the other end of the pull rod is threaded to an inner post 48, a spring 49 is sleeved on the pull rod, the inner end of the spring 49 abuts against the outer end of the inner post 48, the outer end of the spring 49 abuts against the inner plate of the end plate 46, and an insertion rod is welded to the other end of the inner post 48, the insertion rod is inserted into the liner plate.

[0024] In this embodiment, when the inner top rotating plate 43 is rotated, the operator needs to pull the holding rod 47 outward. When the inner top rotating plate 43 is perpendicular to the back plate 32, the outward pulling force on the holding rod 47 is released, and then the insertion rod will be re-inserted into the back plate 32 under the drive of the spring 49, thus ensuring the fixing effect of the filter cloth.
